The hex color #0307B1, a dark blue, presents some accessibility challenges, particularly in text applications. Due to its low luminance, it offers insufficient contrast when paired with standard light backgrounds like white or light gray. This can make text difficult to read, especially for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #0307B1 for text requires careful consideration of the background color to meet these standards. It is generally advisable to pair it with very light colors such as white or pale yellow to ensure readability. For interactive elements like buttons, proper focus indicators are essential to maintain accessibility for keyboard users.
